Any process that stops, prevents, or reduces the frequency, rate or extent of transcription from an RNA polymerase II promoter.

Any process that stops, prevents or reduces the rate or extent of cell proliferation.

Any process that decreases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA (for protein-coding genes) and the translation of that mRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

The process in which a relatively unspecialized cell acquires specialized features of a neuron.

Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of aldosterone.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.

Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process.

Any process that activates or increases the activity of a cysteine-type endopeptidase involved in the apoptotic process.

Any process in which a host organism stops, prevents, or reduces the frequency, rate or extent of viral transcription.

Any process that stops, prevents, or reduces the frequency, rate or extent of neuron differentiation.

Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.

Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.

Any process that stops, prevents, or reduces the frequency, rate or extent of calcium ion-dependent exocytosis.

Any process that stops, prevents, or reduces the frequency, rate or extent of the regulated release of insulin.

Any process that stops, prevents, or reduces the frequency, rate or extent of neurogenesis, the origin and formation of neurons.

The process in which a relatively unspecialized cell acquires specialized features of a cardiac myoblast. A cardiac myoblast is a precursor cell that has been committed to a cardiac muscle cell fate but retains the ability to divide and proliferate throughout life.

The modification of histone H4 by the removal of one or more acetyl groups.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an electrical stimulus.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a glucocorticoid stimulus. Glucocorticoids are hormonal C21 corticosteroids synthesized from cholesterol with the ability to bind with the cortisol receptor and trigger similar effects. Glucocorticoids act primarily on carbohydrate and protein metabolism, and have anti-inflammatory effects.

Any process that stops, prevents, or reduces the frequency, rate or extent of cortisol biosynthetic process.

Any process that stops, prevents or reduces the frequency, rate or extent of dense core granule biogenesis.

Any process that stops, prevents or reduces the frequency, rate or extent of amniotic stem cell differentiation.

The ordered and organized complex of DNA, protein, and sometimes RNA, that forms the chromosome.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

A protein complex that possesses activity that prevents or downregulates transcription.

A stable macromolecular complex composed (only) of two or more polypeptide subunits along with any covalently attached molecules (such as lipid anchors or oligosaccharide) or non-protein prosthetic groups (such as nucleotides or metal ions). Prosthetic group in this context refers to a tightly bound cofactor. The component polypeptide subunits may be identical.
